Part alignment

Hello everyone,

We are having trouble measuring the part. There are big diferences between our and customer's measurements. The customer is using PolyWorks.

I received point coordinates for plane A (5 points) and B (6 points) from a customer (see picture below). For Plane B he also wrote "the plane is on the cylinder with Ø3,5m and we made a plane with 6 points"

How to do iterative alignment correctly?

My alignments:

Many thanks.

  • Do you have the CAD model, and if you do, where is it's co-ordinate system origin when you import it?  As others have said, those XYZ values look like car body co-ordinates.  Usually, for parts like this, the CAD is also supplied in car body co-ordinates which allows you to simply import it and then add auto-vector or auto-surface points, typing in the XYZ values shown.  After typing in the XYZ values, there is a button you can click to find the corresponding vector for each point before creating.
